- SPECIFICATION forming part of Letters Patent No. 530,046, dated November 27, 1894..

Application filed December 1, 1893. Serial No. 492.475. (No model.)

To all whom it may concern:

Be it known that 1, JOHN J. HEYS, of Lynn, county OfESSBX, State of Massachusetts, have invented an Improvement in Heel-Pressing Machines, of which the following description,

in connection with the accompanying draw,

ings, is a specification, like letters and figures on thedrawings representing like parts.

This invention has for its object to improve to the class of machine represented in United States Patent No. 497,497, granted to me May 16, 1893, my improvements simplifying and increasing the durability and capacity of the machine for work. In this my present invention I have provided the heel carrier with suitable means to clamp the heel in a yielding manner after the latter has been fed to the carrier, said heel being clamped while it is being fed into the compressing die, the heel being in practice compressed on all sides.

In my improved machine the'stroke of the parts in compressing the heel vertically is sub stantially the same, and to provide for heels of varying thickness I have arranged to employ a series of tread plates one or more of which maybe added to the carrier according to the thickness of the heel; and I have also combined with the hopper to contain the heel blanks adjusting means whereby said hop per, and with it the heel blank feeding device, may be adjusted vertically according to the effective thickness of the tread plate. I have provided means for securely locking the heel seat die in working position, such locking enabling it to effectually resist any lateral displacement during the time that the heel blank is being compressed.

Other features of my invention will be hereinafter described and designated in the claims.

Figure 1 is a view partially in side elevation but chiefly in vertical section, of a machine embodying my invention. Fig. 2 is a detail showing the adjustable hopper; Fig. 3, a section below the dotted line :12, Fig. 2.

Fig. 4 is a partial front elevation of the machine shown in section in Fig. 1. Fig. 5 is a detail of the devices for moving the feeder. Fig. 6 is a detail showing the dies in plan View, the carrier and the hopper adjusting intervention of shoes or brackets 17, b. devices thus far described by letter with the mechanism being in section in about the line 00, Fig. 4. Figs. 7, 8, 9 and 10 show respectively a side elevation, plan, and longitudinal section and end view of the blank feeding mechanism. Fig. 11 is a detail illustration of the heel seat die and its actuating devices. Fig. 11 is a detail of the rocker lever H; Fig. 12, details of the heel seat die. Fig. 13 is an under side view of the stationary cross head or abutment. Fig. 14 is a plan view looking upon the dies closed with the heel seat die locked in position; Fig. 15, an enlarged detail of the heel seat die. Fig. 16, is a detail showing the adjustable connection between the links it and the frame-work. 6

The side pieces A of the frame are connected at their upper ends by a stationary cross head A, and at their lower ends by a fixed cross head A the said cross heads be ing firmly connected together by rods A A held in socketsin the side frames, said rods serving also as guide rods for the movable cross head B to be described. The machine has a suitable shaft B driven in any usual manner, said shaft having as shown apinion B which engages a toothed gear B fast on a crank shaft B connected by link 15; to the pin B forming the junction between the two links 13", B constituting what is called a togglejoint, said links beingjointed respectively to the movable cross head B and the lower fixed cross head A as shown,'through the The exception of the shoes or brackets, are common to my patent referred to.

I have connected the frame sides by means of a girt C to which I have secured a bracket C, said bracket having a cam slot 2, shown as having substantially straight portions at 0 bottom and top connected by an inclined portion, see Fig. 1, and said bracket has conplate C shown best in Fig. 11.

The under side of the cross head A, see 5 Figs. 1 and 13, is in this instance shown as recessed at a to receive the top of the heel seat die D, and said recess is made deeper at its 'nected to it as shown bv stud bolts 3, a cam center as at a to receive the head of the bolt 03, used to confine in position on the heel seat die its detachable face 01, see Fig. 15, said.

faces being readily changed for heels of different sizes, said faces having preferably at their backs projections as l, to enter a recess in the main body of the heel seat die, said projections accurately positioning the faces.

The movable cross head has mounted upon it carriers 2', t, which carry edge compressing diesj,j, see Fig. 6, said carriers being connected by links 7i; with the frame-work, substantially as in my said patent, but herein I have provided for holding said dies in working position in a novel manner, viz:--by bolts 5, 5, pinned or jointed preferably by thumb pins 6 at one end to the said dies and extended through the said carriers, said bolts having nuts 7 applied to their ends, said thumb pins being readily removable whenever it is desired to change the dies j,j.

In practice the die carriers are moved toward and from each other as the cross head B is raised or lowered as provided for in my said patent. In this instance of myinvention the die carriers 5, i, have at their front ends, see Fig. 6, heavy lugs or projections 8, to the inner sides of which are applied suitable hardened gibs 10, which, as the carriers 11, i, are made to approach each other, act upon and grasp the outer side of the breast guide 61 connected to one end of the body of theheel seat die, said breast guide being preferably integral with said heel seat die, as thereby better work may be done than when the said heel seat die and breast gage are made as separate pieces.

The shape of the breast gage is best shown in Figs. 12 and 14:, and it will be seen that said gage has an angular edge 12, which as the movable cross head B rises, passes close to the breast edges of the tread plate 14, said edge 12 enteringa groove or depression 15, see Fig. 12, below the top of said tread plate. The edge referred to is useful because it acts to cut off or remove any adhering fibers of the leather which may have remained on the tread plate.

In practice, the compressing movement of the parts in compressing a heel vertically, will be the same, but heel blanks will from time to time vary in thickness, and to pro vide for this I increase or decrease the thickness of the tread plate, thelatter being readily detachable from the heel blank carrier to be described. In practice I find it very convenient to make up the tread plate of a series of these plates, two or more, I having shown two plates in the drawings.

The heels to becompressed will be put into a hopper E, substantially the same as in my said patent, the sides of said hopper being adjustable by screw 16 on an arm 17 provided, see Fig. 2, with a scale, which, co-operating with the lower end of the side of the hopper, indicates the proper position of the hopper for heel blanks of different height.

The foot of the arm 17 is in this instance secured by bolt 18 to an adjustable table E,

on which slides the heel feeding mechanism to be described, said table having a depending shank 19, see Fig. which shank is fitted to slide vertically between guides 20, a screw 21 resting on a suitable seat 22 and engaging said shank being employed to adjust said table vertically and with it the hopper, to thus correctly position the heel blank feeding mechanism according to the thickness of the tread plate and the thickness of the heel blank, said screw constituting one form of adjusting device, but for the screw, I may use any suitable equivalent device. The heel feeder, in this instance of my invention, conessentially of a plate e constituting a heel blank support, see Figs. 7 to 10, said plate, it lying when at rest substantially under the lower open end of the hopper E, being slotted at 24 for the passage through it of a stud 25 secured in a pusher c, said pusher acting against the edge of the lowermost heel blank in the hopper, and moving it laterally into position on the tread plate referred to, it lying on a projection of what I denominate the heel blank carrier G. The stud 25 is surrounded between the pusher and support, see Fi 9, with a friction washer 26, preferably of leather or rawhide, and be low this supportsaid stud is surrounded by a second washer 27 which may be of wood, said washer being acted upon by a spring 28, controlled as to its pressure by suitable nuts 29, said washers constituting a friction de vice which will cause the supporting plate to be moved until obstructed, in unison with the pusher, as the latter is actuated by the link 30, jointed to the compound lever 31, 32, see Figs. 1 and 5, said lever constituting part of the actuating mechanism for the feeding mechanism. The arm 32 is fixed to a rock shaft 33, mounted in suitable bearings 83 on the frame, said rock shaft having an arm 34 provided with a roller or other stud which enters a cam groove, not shown, in a suitable cam disk 36, substantially such a disk as in my said patent.

The arm 31 is jointed by pin 37 to the arm 32 and said arm 31 is made adjustable as to its effective throw by an adjusting device 38 shown as an adjustable screw, one end of which acts against arm 31 when the pusher is being moved forward to feed a heel blank, the screw 38* in ear 39 of arm 32 acting on the arm 31 when the pusher is being retracted. The screw 38 acts to always return the pusher to a common starting point, but by adjusting said screws so as to provide for more or less lost motion between them and the arm 31, I may move the pusher more or less in the feeding operation according to the size of the heel blank. The stop 40, see Fig. 9, arrests the support e in a definite position as the pusher is retracted. In operation, the supporting plate 6 is moved forward until its end meets the tread plate then opposite it,

.and thereafter the pusher by its continued movement pushes the blank from said support onto the tread plate, and under the heel seat die to be described.

To insure the positive retraction of the support e the latter has been provided with ratchet teeth as at 41, see Figs. 7 and 8, which are engaged by a pawl 42 pivoted on the pusher and having a pin 43 which rides on a cam plate 44, the latter eifecting the disengagement of the pawl from the ratchet teeth as soon as the said support has been retracted sufficiently to not interfere with the movement ofthe heel carrier, and thereafter the further movement of the support in the same direction is effected by the friction device before described. The carrier G is herein represented as a bent lever pivoted at G on a suitable bracket G secured to the movable cross head B, as best shown in Fig. 4. The lower end of lever G has a roller or other stud G which enters cam groove 2. The pin G also serves as the fulcrum of a rocker lever H having a depending arm h which co-operates with the portion 56 of the cam plate 0 said rocker lever having also an arm 72, which is jointed at 45 to a block 46 into which is adjustably screwed one end ofa rod 7?, the head of which enters a spring case 7L containing preferably a spiral spring it, see Fig. 1, said case having that end through which the link passes made detachable, the rod acting against one end of said spring, said spring and rod constituting a yielding or spring link.

The upper end of the spring link is jointed to a lever k pivoted on a link it mounted on the carrier-G, the innerend of lever 77 being jointed at 48 to the combined heel seat die and breast gage.

The rocker lever H, see Fig. 11,- has near the upper end of arm h and at the innerside of said arm a shoulder 50.

Viewing Fig. 1, showing the movable crosshead in its lowest position; it will be seen that the lower end of arm h is under the portion 56 of the cam plate 0 audit will be assumed that a heel blank has been pushed between the tread plate and the heel seat die, and is lightly held there by the stress'of spring h, but the breast of the heel blank may not be against the breast gage. In this condition the cross head B will be moved vertically and the arm h' in the first part of such movement will strike the portion 56 of the cam plate O and the rocker leverH will be turned, and when the lower end of the arm h rests against the said portion 56 the point 45 of the yielding link will have been moved to the left and downward, see Fig. 1, whereby the rod h is retracted until its head-by contact with the case pulls the latter down to release the heel blank and let it move by gravity until the breast of the blank rests against the breast gage. This done, in the further upward movement of the carrier, the roll G will enter the inclined part of groove 2, and the carrier will be moved on the pivotal point G in such direction as to carry the heel blank into position between the edge dies, and in such move- :and starts the latter from the carrier.

the heel seat die.

referred to.

ment the relative positions of'the centers of the lower end of the yielding link and the carrier will result in compressing the spring h thus clamping or pinching the heel blank between the heel seat die and tread plate,

said clamping action continuing until after the heel has been putinto position and compressed, and the carrier has thereafter begun its outward movement.

As the carrier with the compressed heel is being moved outwardly to retract it from the die,.the lower end of arm h then resting against the portion 56 of the plate C ,the

heel seat die will begin to rise, for the strain ;on the spring link is then exerted downwardly, the said heel seat die rising until the 'conveXed face of the plate at is raised suificiently to free the .compressed blank. Substantially as the heel blank carrier reaches then on the blank carrier, and while the pressure on the compressed blank is relaxed, the pusher pushes the edge of the uncompressed blank against the compressed blank The heel seat die is kept elevated until a small portion of the uncompressed heel blank. is lodged between the tread blank and the heel seatdie, and this effected, the heel seat die will be caused to descend, act on and clamp the uncompressed heel blank, and it will hold said heel blank compressed by a strain measured by the spring hflwhile the pusher in its continued forward movement pushes the heel into place between the tread plate and It is important to hold the uncompressed blank frictionally, as stated,

for otherwise in the quick movement of the machine the said heel blank could not be properly positioned upon the heel blank carsaid rocker lever is given a quick turn for a slight distance in a direction to increase the tension of spring h, and at the same time put the lower end of arm 7t under the portion 56 The uncompressed heel blank in coming into place between the tread plate and the heel seat die acts against thecompressed blank then on the tread and knocks the same off.

The cross head A has attached to its front side by suitable set-screws 100 a guide 101 behind which the heel seat die rises while the heel blank is being compressed, said guide preventing any outward slipping of said die, said guide being shown as notched to embrace and steady the lever b I have before described that the lever 31 32 is or will be adjusted one part on the other-to enable the pusherto operate prop- .erly with a heel-blank of a certain size, in

order that the pusher may correctly place the heel blank upon the carrier, and to properly effect this adjustment accurately, the operator, prior to adjusting the lever 31, 32, will rotate the shaft B until the point n shown as marked on the gear B registers substantially with the finger n and with the shaft in such position, the pusher being way forward, the operator will make the final adj ustment to adapt the pusher for the size of the heel blank thereafter to be used.

The act of compressing the heel blank edgewise requires the exertion of, it will be understood, very considerable power, and consequently to resist the strain the mechanism employed must be very strong and rigid, and I have aimed to provide means whereby the carriers upon which the edge-com pressing jaws are mounted may resist excessive strain, and to do this in the best and most economical manner, I have provided the upper end A of the frame-work of the machine, see Fig. 4, with an car which receives a fulcrum pin 66, which pin pivots the link of the carrier to the frame-work. In practice I prefer to make this pin with eccentric ends 66, as best shown in Fig. 16, said ends receiving upon them the links it, there being two such links asherein represented in connection with each carrier 2'. The body of said pin will preferably be of greater diameter than its eccentric ends and will have a driving fit in said ear. By fixing said pin so that it cannot rotate while the machine is in use I am enabled to throw all the wear on the pin and links, and to compensate for this wear and also to enable the faces of the edge-compressing jaws to be accurately adjusted to properly co-operate withthe heel blank carrier, I may remove said pins and rotate them more or less, their eccentric portions adjusting the carriers toward and from each other as may be required. I
